TTSPORT Race Calipers: TR65, TR40 & TR20 Built for CTCC Champions
On a race track, braking decides who wins and who doesn't. TTSPORT's three race calipers — TR65, TR40, and TR20 — were developed and proven in China's CTCC touring car series and refined with input from a European brake designer. Each one is built for a specific job on the car, not as a one-size-fits-all kit.
Whether it's a hard stop at the end of a long straight or a run of tight, connected corners, the target is the same: a brake pedal that feels the same on lap 20 as it did on lap 1. That consistency is what the TR65, TR40, and TR20 are engineered around.
Race-Proven: CTCC Results with TTSPORT
These calipers didn't start on a bench — they started on the grid. Teams running TTSPORT have logged class wins, team titles, and podium finishes across the 2025 CTCC China Cup season, through high-heat, high-speed, sustained race conditions where brake fade shows up fast if the hardware isn't right.
Consistent bite point, a linear pedal, and brake torque that doesn't fall off lap after lap — that's the feedback TTSPORT gets from the teams actually racing with it, not marketing copy.
TC1 class — class champion and team champion in both Round 1 and Round 2
TCS class — 3rd place (Round 3) and 2nd place (Round 4)
TCS class — Round 6 class champion, Round 7 class runner-up
Three Calipers, Three Jobs
TR65 — Front 6-Piston Monoblock
The flagship of the lineup, built for cars pushing the hardest braking loads. It's machined from a single forged aircraft-grade aluminum billet on a five-axis CNC, with a 6-piston differential-bore layout that spreads pad pressure evenly across the surface for more precise control. Geometric H-shaped bridge ribs add rigidity and resist heat-induced flex, and multi-channel venting keeps temperatures in check through repeated hard stops. It pairs with either racing steel rotors or carbon-ceramic discs, depending on the car.
TR40 — Front 4-Piston Monoblock
The all-around option — built to work on track and stay livable on the street. Same one-piece forged construction for a strong strength-to-weight ratio, but with a 4-piston differential-bore design tuned for a more linear pedal and lower thermal fade. Internal fluid passages keep the hydraulic circuit clean and simple, and a quick-release pad system means techs can swap pads without pulling the whole caliper off the car. Compatible with both racing steel and carbon-ceramic rotors.
TR20 — Rear 2-Piston Split-Body
Rear brakes don't need six pistons — they need balance. The TR20 uses a split-body forged design that's simpler to manufacture and service, with a 2-piston differential setup that keeps rear brake force even and helps prevent lockup under hard braking. It's compact enough to fit tight rear wheel wells across a range of chassis, plated to resist corrosion and heat, and matched to run alongside either the TR65 or TR40 up front for a balanced front-to-rear setup.
The Engineering Shared Across the Lineup
All three calipers share the same design philosophy, developed with a European brake designer and built around a few core ideas: monoblock or split-body forging combined with five-axis CNC machining for tight tolerances, a 12-hour stress-relief process that keeps deformation low under sustained heat, differential-bore pistons that even out pad wear and extend service life, H-shaped reinforcement ribs with multi-channel venting for heat management, quick-release hardware for faster trackside pad changes, and compatibility with both racing steel and carbon-ceramic rotors depending on what the car and budget call for.
Why Teams Run TTSPORT
None of this is theoretical — it's been through professional competition, and the same technology carries over into calipers people run on street cars and long highway drives. TTSPORT has spent over 20 years focused on braking hardware, and that experience shows up in how these calipers hold up when the track gets hot and the laps keep coming.
